Patent

CA 2238600

A stator winding has a plurality of conductor members forming coil ends, and each of the conductor members of the coil ends is hardened and heat treated to have hardness which changes along the length of conductor members. Therefore, the stiffness of the coil ends changes and resonant vibration of the stator can be reduced.

Un enroulement de stator a une pluralité d'éléments de conducteur formant des têtes de bobine, et chacun des éléments de conducteur des têtes de bobine est durci et traité à la chaleur de façon à avoir une dureté qui change sur la longueur des éléments de conducteur. Par conséquent, la rigidité des têtes de bobine est modifiée et la vibration de résonance du stator peut être réduite.
